+### Description
+
+Spark support Hive format in `CREATE TABLE` clause and `TRANSFORM` clause, Hive format support 


Spark supports Hive format in `CREATE TABLE` clause and `TRANSFORM` clause, to specify serde or text delimeter.

cloud-fan · 2021-04-21T07:54:45Z

+
+* **row_format**    
+
+    Use the `SERDE` clause to specify a custom SerDe for one table or processing inputs and outputs data. Otherwise, use the `DELIMITED` clause to use the native SerDe and specify the delimiter, escape character, null character and so on.


shall we put it in Description at the beginning?

we can merge this with the next one. SERDE serde_class

~~In this case, shall we add a reference to this sql-ref-syntax-hive-format.md into sql-ref-syntax-qry.md?~~

Oh, got it. I saw @cloud-fan 's comment, We don't need to put it in the menu page. Nvm.

Yea, refer this in other menu doc is so strange and it's refer in two syntax doc with different type.

how about this

There are two ways to specify the `row_format`: 1. Use the `SERDE` clause to specify a custom SerDe class 2. Use the `DELIMITED` clause to specify the delimiter ... and so on for the native text Serde.

Year, more clear

+* **row_format** 

-    Used for escape mechanism.
+    All descriptions about syntax in `row_format` can refer to [HIVE FORMAT](sql-ref-syntax-hive-format.html)


How about Specifies the row format for input and output. See [HIVE ROW FORMAT](...) for more syntax details.?

Could you add the screenshot of the new page in the PR description?

maropu · 2021-04-22T15:05:29Z

NOTE: I'm planning to backport this PR and #31010 into branch-3.1/3.0 because I think these document pages are useful for users.

@maropu shall we have a single backport PR or two?

maropu · 2021-04-23T06:00:57Z

They have different jira tickets, so I think its better to backport them separately. Could you? @AngersZhuuuu

maropu · 2021-04-23T06:01:46Z

Anyway, late lgtm. Thank you, @AngersZhuuuu

Hmmm, have conflict? need me to create backport PR?

maropu · 2021-04-26T08:04:00Z

yea, yes. I couldn't cherry-pick them into the previous branches.
